“…The N-CDs were used for the determination of Fe +3 with a LOD of 100 nM. Chai et al [136] proposed the fabrication of N-CDs from the traditional Chinese medicine "Gastrodia elata", with chrysanthemum as a catalyst, using a hydrothermal method, which was applied for the detection of phydroxybenzaldehyde (PHBA) with a LOD of 63 nM. Jia et al [137] described the preparation of fluorescent N-CDs, following a one-step pyrolysis method, from black soya beans with 38.7% Φ.…”

Among carbon-based nanomaterials, carbon dots (CDs) have received a surge of interest in recent years due to their attractive features such as tunable photoluminescence, cost effectiveness, nontoxic renewable resources, quick and direct reactions, chemical and superior water solubility, good cell-membrane permeability, and simple operation. CDs and their composites have a large potential for sensing contaminants present in physical systems such as water resources as well as biological systems. Tuning the properties of CDs is a very important subject. This review discusses in detail heteroatom doping (N-doped CDs, N-CDs) and the formation of metal-based CD nanocomposites using a combination of matrices, such as metals and metal oxides. The properties of N-CDs and metal-based CDs nanocomposites, their syntheses, and applications in both chemical sensing and biosensing are reviewed.

“…Fluorescence quenching includes static and dynamic quenching. Static quenching refers to the combination of fluorescence molecules and quenching agents to form non-luminescent ground-state complexes [53], which follows the Lineweaver-Burk equation in equation (2). In general, the UV-visible spectrum of the fluorescence substance will change with the addition of a quencher while the fluorescence lifetime remains unchanged and the quenching constant decreases with the increase in temperature [54].…”

Silver is widely used in medical materials, photography, electronics and other industries as a precious metal. The large-scale industrial production of silver-containing products and liquid waste emissions aggravate the environmental pollution. Silver ion is one of the most toxic metal ions, causing pollution to the environment and damage to public health. Therefore, the efficient and sensitive detection of Ag+ in the water environment is extremely important. Sulfur-doped carbon nitride nanosheets (SCN Ns) were prepared by melamine and thiourea via high-temperature calcination. The morphology, chemical composition and surface functional groups of the SCN Ns were characterized by SEM, TEM, XRD, XPS, and FT-IR. The fluorescence of SCN Ns was gradually quenched as the Ag+ concentration increased. The detection limit for Ag+ was as low as 0.28 nM. The quenching mechanism mainly is attributed to static quenching. In this paper, SCN Ns were used as the fluorescent probe for detecting Ag+. SCN Ns have successfully detected Ag+ in different environmental aqueous samples and cells. Finally, SCN Ns were further applied to the visual quantitative detection of intracellular Ag+.
